improved 90% within 1 week, stopped taking the meds in 3 days and after 3 months I'm normal except with some occasional heartburn. Strange enough though when I went on vacation and it went away as well. No smoke on vacation and I didn't eat 3 hours before bed. I had a long break from the vaporizer and and within 2 days of firing it up I'm getting heartburn again. Maybe it is the munchies and eating too late or there is something about the vapor that irritates the throat sphincter. Still trying to figure that out since giving up smoke would be a drag. Apple cider vinegar cures many people and I always found that green apples made me feel better. Something about too little acid causes the same symptoms or that the vinegar helps you digest quicker and properly. I also found that B12 Complex helped me immensely along with Folic Acid. On vacation I didn't have the vinegar, I ate and drank everything I wanted including Danish hot dogs and beer, just took the B12 and the Folic Acid and didn't eat close to bedtime, ate a big breakfast but stayed away from Fruits in the morning and I was 100% normal, no IBS no GERD.
